Application filed January 9, 1925.

My present invention pertains to shuttle binding means; and it has for its general obgect to provide an lmproved shuttle bmd- 111g means characterized by a yielding strip J! J. i and possessed .oi the capaclty 0L withstanding hard usage and of the ability toubring lerent kinds of looms.

Similar letters and numerals designate corresponding parts in. all of the" x' 'ie'ws of the drawings;

I illustrate in. the drawip'gs a portion of a lay A, together with the bottom race plate Serial No. 1,475.

B and the back C of a shuttle box, the said back being connected by bolts D and being detachable and adjustable. I also show a picker stick E movable in slot 2, Figure 9 and a picker 1, together with a shuttle 3 which in Figures 1 and 2 has fully entered the shuttle box.

A lug at projects from a pendent portion on the race plate B, and carries an upright stud 5 on which my shuttle binder generally designated by 6 is mounted to swing. The said binder G is detachably held in position by said stud, and the binder is prevented from rising on the stud by a washer secured by a screw 7 on the upper end of the stud. A screw 8 bearing in the lug is used to adjustably hold the stud 5 in position and is equipped with a lock nut 8, the lug at being slotted at 1, Figure 1.

Among other elements the binder 6 comprises a cast metal body in the form of a strip which is slotted at F for the admission oi the weft or filling commonly used in looms. The said metallic strip is lined atits inner side with two flexible strips 9 and 10, oi leather, the said strips 9 and 10 being adapted to prevent contact of any part of the metallic shuttle. The meeting ends of the leather strips 9 and 10 are held in a notch 1O in the metallic binder body by a screw 11 screwed between the end portions of the strips. Consequently when either of the leather strips becomes worn it can be readily removed without affecting the other leather strip and may as readily be replaced with a fresh leather strip. The metallic binder body has a portion 12 spaced, as designated by 9", from that portion of the leather strip 10 that bears against the forward side of the shuttle 8'. Said portion 12 has acurved end aperture'd to receive a bolt 13 which also extends through coincident apertures in the lining strip 10 and an interposed spring plate 15, Figure 3, and is equipped with a nut as shown. The strip 15 is not employed in the embodiment shown in Figures 1 and 2.

In the space 9 is a plate 16 which backs the leather strip 10 and is carriedb'y two legs 17 guided and loosely movable in an aperture in the body portion 12 A; web 22 eat ends between the legs 17, Figure 13, p n V 21 in. a rubber spring, to reta'in'. saicl. s p ng'between' said' legs'-,-Figu-r'e '11". Thesaid rubber spring' backed by a screw 23 having. a flat of diskli'ke for ward portion and is also movable in said aperture in portion 12. The screw 28 bears in a laterally-piejecting frame 19 on the binder portion 12 and is equipped with a lock nut 23*. Said frame 19 has connected at 19 a ilat spring or spring strip 26. Mani testly when the shuttle contacts with the binder swell, the spring 26 will bear against the front of the lay A. That inczeases the pressure of the binder swell on the shuttle and assists in slowing down the shuttle. Then when the shuttle is near the end of the box or the picker 1, the s iuttle shoulder contacts with the yielding strip 10, and the plate 16 moves against action of spring 20 and incre; the pressure against the shuttle. In the modification of Figure 4, a flat spring 28 e:':tends along; behind strip and strengthens the strip 10, and the spring is used directly behind spring 28. Two holes are provided at 29, Figure for the insertion of a pointed instrument through the medium o1 wnich the spring 28 can be moved toward. the right to increase the pressure on the leather strip 10. The binder can be used with or without the spring 28 inasmuch as the rubber spring can be regulated to exert the proper pressure against the plate 18 and leather strip 10 and enable the latter to operate to the best advantage. Obviously when the rubber spring; 20 is impaired it can be readily removed and replaced with a fresh spring.

In the embodiments shown in Figures 3. at 9 and 10, the spring or spring strip 26 secured by a unit as 23* on the screw 23 and against the outer end of the binder projection 19.

Adjustably connected. at 29* of the lay is a bracket 30 which is relatively arranged as illustrated. The said bracltetcarries a bolt in an aperture S3 or the bracket, and a sleeve on the bolt 32 has a longitudinal slot 34; Figures 6 and 7, to receive the end port-ion ot a coiled spring said spring loosely surrounding said sleeve as will be readily understood. On the spring 35 is an upwardly reaching arm PM. The sleeve or bushing referred to is provided with an angular head for the application of a wrencl'i so that the coiled spring can be readily regulated as occasion demands. The arm 37 provided with an angularly disposed portion at its upper end with rests in an eye 38 carried near the end of the binder body and prevents bearing of the binder on a lateral projection 39 on a plate 39 connected at 40 to the lay, so that no wear will take place on the binder. This provision is important inasmuch as the arm 37 serves to assure the shuttle properly entering the shuttle box without retardation of the shuttle but so that the shuttle is alongside the binder and fiat on the race plate B as shown in, Figure 2. As will be $51 to the sword understood from'lligure 9 when the shuttle is not in the box the binder end occupies its normal position which is against the frame or plate l best shown in Figure 9.

The extent of movement of the binder is made clear by Figure 1, and it will be understood that when the binder is swung or forced outuu y by the shuttle entering the box, the arm 42 will be moved to turn the shaft 4-3, journaled at 4 1 in plate 89 and lower the dagger so that in the beat up iovement oi the lay the dagger will not ongage the stop member of the knock oit' ehanism. The binder is limited by the binder finger or protecting rod in well known manner. When the picker throws or picks the shuttle from the end of the box the pres sure exerted by the strip 10 on the shuttle shoulder and on the binder swell releases at once. The shuttle moves along the back plate of the box and reed in line with the plate and straight through the shed and into the opposite box. The illustrated sloping f the strip 10 covers the shuttle filling groove and eye so as to prevent the thread from flashing away from the shuttle eye and groove w iich will result in breaking, kinking or slackening the thread.

As will be understood from Figure 5, I provide slots a in the lining strips 9 and 10 tie said slots being out through the lining and allowing ample space for the thread to play. As illustrated the binder lining has a tongue which passes through the binder slot and is secured on the front of the binder ata Figures 1 and 2, this provision being: made in order to prevent sidewise movement of the binder lining on the binder.

The binder 1-6, Figures 9 and 10, is made in a slightly different shape "from the binder 6 so as to bring the point at which the lining 47 in Figures 9 and 10 can yield to a slightly different point. It will also be noticed that the binder stud 5 is differently positioned in Figures 9 and 10. The binder swell, however, is adapted to be swung out-- ward at the point 42.7. This will be better understood when it is stated that the shuttle contacts or engages the yielding strip so that the outer end of the spring 26 will be swung: toward the lay and will bear against the front of the lay. Manifestly this will assist in slowing down the shuttle and limiting the movement of the binder as is desirable. The binder 46 is further limited by the binder finger 42 in cooperation with a stop mounted on the shaft 43 so that when the shuttle engages or contacts with the yielding strip the plate 16 behind the strip moves against the action of the rubber spring 20. Said. spring 20 exerts its pressure on the lining 47 so that the pressure of the binder swell on the shuttle isreduced. The binder hasan eye 38 to receive the angularly disposed. portion of an arm 37 the lower end of Which is disposed in an eye IS in the outer end of a bracket 30. At 49 is a thumb or guard above the eye 4-8 and relatively arranged to the arm 37 for controlling the arm, the said arm 37 having a coil at 50 to facilitate in certain of its portions in the eyes 38 and 48 so that the arm can be removed from both eyes when necessary.

The spring 20 may be varied as to tension by adjusting the screw 23 in the modification of Figure 4.

The spring 28 and plate 16 are not used together on the same binder, but the spring 28 can be used on all the binders.

The slot 1% in the strip 10 is to adjust or take up the stripi. c., if when in use the strip becomes loose or spreads out so it "an be taken up by the slot represented in Figures 1 and 3. The binder can be used with or Without interposed spring plate 15. In the binder, Figure 4;, the spring 28 is always used. T he binder can rather be used Without the spring 20 than the spring 28.
